Description
Technical field
The invention belongs to agricultural plantation technology field, and in particular to a kind of spring maize method for treating seeds and plastic-film-covered cultivation side
Method.
Background technology
Corn also known as maize, ear of maize, maize etc., belong to grass family Zea.Corn rich in carbohydrate, protein,
The human body required nutriment such as vitamin, dietary fiber, mineral matter, especially its contain abundant luteole, linoleic acid and
Glutathione.Have shown that luteole is that the constituent of human retina, linoleic acid are the required fat of needed by human body in relation to research
Fat acid, glutathione, which have, improves immunity of organisms and anticancer function, dietary fiber with delaying blood glucose rise and removing enteron aisle
The functions such as rubbish.It may be said that corn whole body is precious, play an important roll to adjusting human body abnormal metabolism.
Corn is that important cereal crops, forage crop, light industry crop are the required important grain of world population
One of food and the raw material of industry, and one of widest cereal crops are distributed in the world, its cultivated area is only second to wheat and water
Rice two occupies the 3rd.China is located in corn gold growth band, is second-biggest-in-the-world maize production and the consumption for being only second to the U.S.
Big country, in China, corn is even more to have evolved into the first big industrial crops.
Corn divides spring maize and autumn corn according to the difference of implantation time, and spring maize the first tenday period of a month May late April are sowed, and eight
The last ten-days period moon can harvest.Autumn corn cannot be later than sowing mid-July, mid or late October harvest at the latest.Spring maize (spring
Maize) it is the corn that refers to spring sowing for autumn corn, because sowing time is early, is also referred to as in the north early beautiful
Rice.Spring maize is wider in China's plantation region, is mainly distributed on northeast, northwest and the north area of North China, southwestern Hills are also
It is distributed.
Differ greatly between sowing time of spring maize and harvest time region.Generally from south to north, start from mid-February to May
There are the area of sowing spring maize in the first tenday period of a month, during generally with 10cm soil temperatures stabilization more than 10 DEG C sowing be advisable；Harvest time is also
From south to north, from late July to mid-September, successively differ up to more than 50 days.The growth characteristic of spring maize is that seedling growth is slow,
Basal internode is shorter, and fringe position is low, robust plant, and lodging tolerance is stronger；But its fruit ear is big, and single plant yield is higher, high in full summer
Warm, rainy season, easy infection leaf blight, helminthosporium maydis, especially in cool and cold climate then easy infection head smut and smut.
For northern area, due to the limitation of regional climate temperature and rainfall, usually to wait until late April
It can plant spring maize, and harvest time then will be to even September at the bottom of August, this has seriously affected the plantation opportunity of autumn corn, leads
Northern area corn planting is caused to be typically only capable to complete one batch.Although develop in the prior art many for the single batch of production of raising corn
The technology measured and be modified to corn seed, but cannot all solve the present situation that northern area realizes two batches of corns of year kind.
The content of the invention
For this reason, the technical problems to be solved by the invention be to provide it is a kind of improve corn seed cold-resistant and drought resistance with
It is adapted to the method for treating seeds of north；
Second technical problem to be solved by this invention, which is to provide one kind, can realize that northern area spring maize is planted in advance
The spring maize covering cultivation method of plant.
In order to solve the above technical problems, spring maize method for treating seeds of the present invention, this method comprises the following steps：
(1) take spring maize seed to immerse lactic acid aqueous solution, and immersion treatment is carried out under the conditions of microwave radiation；
(2) corn seed after infiltration is dried to water content under vacuum condition and is less than 10%；
(3) dried corn seed is placed under low temperature, drying condition and carries out routine preservation, you can.
In the step (1), the microwave power of the microwave irradiation step is 100-200W.
In the step (1), the temperature of the soaking step is 40-50 DEG C.
In the step (1), the mass concentration of the lactic acid aqueous solution is 10-20wt%.
In the step (1), the quality of the corn seed and the volume ratio relation of the lactic acid aqueous solution are 20-30g/
L。
In the step (1), the time of the soaking step is 3-5h.
In the step (2), the temperature of the drying steps is 50-60 DEG C.
The invention also discloses application of the spring maize method for treating seeds in spring maize growing and cultivation field.
The invention also discloses a kind of spring maize covering cultivation method, include the following steps：
(a) seed after the processing of above-mentioned spring maize method for treating seeds is chosen, with Seed soaking 8-10h before sowing,
Then add seed coat agent and be coated processing；
(b) it is whole thin flat in a conventional manner by planting soil timing tillage, root stubble, stone are removed, to table soil pine in small, broken bits
It is soft, with Meteorological effect；
(c) base manure is used sufficient in a conventional manner, and the base manure is farm manure, organic fertilizer or farmyard manure；
(d) after leveling land, trench digging is carried out for broadcasting, and controls furrow width 60-65cm, enough depth 10-15cm；Monoseeding is beautiful in ditch
Rice, controls spacing in the rows 21-28cm, 4000-5000 plants/acre of density；
(e) watering, herbicide spraying, then cover mulch after having planted；The covering 1-2 row corns per film, after planting with the wind
Reality is buried in overlay film, film both sides with soil；
(f) after overlay film, after the expansion of the first leaf of seedling, timely rupture of membranes puts seedling, puts after seedling and obturages seedling hole, and observes corn life
Long situation, in due course watering, fertilizing, prevents pest and disease damage；
(g) waste film is thoroughly removed after harvest corn, purification soil, prevents farmland pollution, you can.
In the step (e), the mulch is polylactic acid film, and the mulch breadth is 80-100cm, thickness 0.006-
0.008 millimeter.
Spring maize method for treating seeds of the present invention, soaks spring maize kind under microwave radiation auxiliary with lactic acid solution
Son, processing is modified to the performance of seed, and experimental data is shown, the side of the present invention handled spring maize seed
Formula, can effectively improve drought resisting and the cold tolerance of corn seed, even if in northern area, can also be implemented in the kind of late February
Plant, to ensure shifting to an earlier date significantly for harvest time.Importantly, method for treating seeds of the present invention can also effectively improve spring jade
The per mu yield of rice, and the form for harvesting product is preferable.
Spring maize cultural method of the present invention, using covering with ground sheeting Adverse Resistance Cultivation new technology, is carried out with polylactic acid film
Plastic-film-covered cultivation, can make full use of thermal energy, nutrient, moisture, have soil moisture conservation to heat, can be with water-saving, province's fertilizer, moisturizing, suppression weeds life
It is long, reach the effect of increasing income.
